Product Details:

REXROTH 4WE10J31 belongs to WE10 series direct operated 4-way solenoid directional spool valve, size NG10, J spool function, subplate mounting conforming to ISO 4401-05 standard. It adopts wet-pin solenoid design and spring centering structure, widely used for hydraulic cylinder forward/reverse movement and hydraulic motor rotation direction switching on industrial machinery. This legacy valve version is discontinued, available stock are refurbished spare units for injection molding machines and heavy hydraulic production lines.

This directional valve changes the flow path of hydraulic oil by energizing or de-energizing the solenoid. J spool configuration means P connected to A, B connected to T at one actuated position; P connected to B, A connected to T at the other actuated position, all ports closed at neutral position. The wet armature solenoid is immersed in hydraulic oil for heat dissipation, featuring stable switching action and long coil service life. Separate power wiring reduces electromagnetic interference generated by servo drives and harsh workshop environment.

The valve body is made of high-strength alloy steel with precision ground spool and sleeve matching pair. NBR standard sealing material, optional FKM seals for high-temperature or special hydraulic media. Maximum working pressure of P/A/B port reaches 315 bar, T port backpressure limit 210 bar, rated flow up to 120 L/min. Vibration-resistant structure and low friction spool design ensure reliable repeated switching response.

All units pass factory inspection including pressure tightness test, switching response test and cycle endurance test before shipment to adapt to long-time multi-shift hydraulic system operation.

It is widely used on injection molding machines, hydraulic presses, automotive fixture clamping stations and metallurgical forming equipment. Typical application scenarios include hydraulic actuator direction control, spare replacement for aging Rexroth hydraulic systems and hydraulic machine retrofit. Automation integrators select this Rexroth valve for its classic J spool function and stable heavy-duty hydraulic performance.
